Abstract

A plasma display apparatus and a method of driving the same are disclosed. The plasma display apparatus includes a plasma display panel comprising a first electrode and a second electrode, and a driver. The driver supplies a ramp-up signal in which a voltage gradually rises to the first electrode in a setup period of a reset period, supplies a ramp-down signal in which a voltage gradually falls to the first electrode in a set down period after the setup period, and supplies at least one reset stabilization signal to the first electrode in a period before the ramp-down signal is supplied after the ramp-up signal is supplied.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A plasma display apparatus comprising:
 a plasma display panel comprising a first electrode and a second electrode; and 
 a driver that supplies a ramp-up signal in which a voltage gradually rises to the first electrode in a setup period of a reset period, supplies a ramp-down signal in which a voltage gradually falls to the first electrode in a set down period following the setup period, supplies at least one reset stabilization signal to the first electrode in a period before the ramp-down signal is supplied after the ramp-up signal is supplied, and supplies at least one sustain rising signal to the second electrode in a period before the ramp-down signal is supplied after the ramp-up signal is supplied, 
 wherein the reset stabilization signal includes a first reset stabilization signal and a second reset stabilization signal, 
 wherein the sustain rising signal includes a first sustain rising signal, a second sustain rising signal, and a third sustain rising signal. 
 
     
     
       2. The plasma display apparatus of  claim 1 , wherein a highest voltage of the reset stabilization signal is substantially identical to a highest voltage of the sustain rising signal or a highest voltage of a sustain signal supplied to the first electrode or the second electrode during a sustain period. 
     
     
       3. The plasma display apparatus of  claim 1 , wherein
 a width of the first reset stabilization signals is different from a width of the second reset stabilization signals. 
 
     
     
       4. The plasma display apparatus of  claim 1 , wherein
 a width of the first sustain rising signals is different from a width of the second sustain rising signals. 
 
     
     
       5. The plasma display apparatus of  claim 4 , wherein a width of at least one of the reset stabilization signal or the sustain rising signal is smaller than a width of the sustain signal. 
     
     
       6. The plasma display apparatus of  claim 1 , wherein
 a voltage magnitude of the third sustain rising signals is different from a voltage magnitude of the first and second sustain rising signals. 
 
     
     
       7. The plasma display apparatus of  claim 1 , wherein the at second reset stabilization signal and the first and second sustain rising signal are overlapped in at least one part. 
     
     
       8. The plasma display apparatus of  claim 7 , wherein a difference between supply time points of the first reset stabilization signal and the second sustain rising signal is 100 ns to 600 ns, and
 a difference between termination time points of the second reset stabilization signal and the second sustain rising signal is 100 ns to 600 ns. 
 
     
     
       9. The plasma display apparatus of  claim 1 , wherein
 during a time period in which a most preceding sustain rising signal in a time order among a plurality of sustain rising signals is supplied to the second electrode, after the ramp-up signal is supplied to the first electrode, a falling signal is supplied in a voltage lower than a peak voltage of the ramp-up signal. 
 
     
     
       10. The plasma display apparatus of  claim 1 , wherein when an ambient temperature or a temperature of the plasma display panel is a second temperature higher than a first temperature, the reset stabilization signal is supplied to the first electrode. 
     
     
       11. The plasma display apparatus of  claim 10 , wherein the first temperature is 0 to 40° C., and the second temperature exceeds 40° C. 
     
     
       12. The plasma display apparatus of  claim 1 , wherein a period rising up to a highest voltage of a sustain signal is substantially identical to a period rising up to a highest voltage of the sustain rising signal. 
     
     
       13. A method of driving a plasma display apparatus comprising a first electrode and a second electrode, comprising:
 supplying a ramp-up signal in which a voltage gradually rises to the first electrode in a setup period of a reset period, and supplying a ramp-down signal in which a voltage gradually falls to the first electrode in a set down period after the setup period, 
 supplying at least one reset stabilization signal to the first electrode in a period before the ramp-down signal is supplied after the ramp-up signal is supplied, and
